UNITED STATES CHARLIE W. SCOTT, 0F LINCQLNTON, GEORGIA.

PLIERS.

Application filed January 6, 1925 Serial No 919-.

To all whom it may concern;

Be it known that I, CHARLIE XV. Soon, a citizen of th United States,residing at Lincolnton, in the county of Lincoln, State of Georgia, haveinvented certain new and useful Improvements in Pliers; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to new and useful improvements in tools, andparticularly to pliers.

One object of the invention is to provide a tool of this characterwherein the jaws are capable of great leverage, and firm holdingability.

Another object is to provide a tool of'this character wherein the jawsmay be easily and quickly released from the work without the necessityof swinging the handles on their pivot.

Other objects and advantages will be ap parent from the followingdescription when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is a perspective View of a pair of pliers made in accordancewith the present invention.

Figure 2 is a perspective view of one of the members.

Figure 3 is a perspective view of another of the members.

Figure 4 is a perspective view of the remaining member.

Referring particularly to the accompanying drawing, the pliers consistof the three parts A, B, and O.

The part A is formed from a single piece of metal, and includes a bodyportion 10 having a vertical slot 11 formed throughout the greater partof its length. Formed on one end of the body 10 is the jaw portion 12,into the inner end of which the slot 11 xtends. In the end of the body,adjacent the jaw portion 12 there are formed the transversely alinedopenings 13 for the pivot 14. The other end of the body 10 diverges, asshown at 15, and formed transversely through this portion are the alinedarcuate slots 16. Beyond the divergent portion of the body there isformed an offest portion 17 which is bifurcated, as shown at 18, and

from this portion 17 there extends the handle shank 19.

Disposed longitudinally within the slot 11 of the body 10 is the shankportion 20, of the member B, one end. of said shank being formed. with.a jaw portion 21, which projects beyond the end of the body 10, inposition to co-operate with the jaw 12. The other end of the shank 20 isformed with a fan-shaped portion 22, the curved edge of which isprovided with a series of rack teeth 23, said fan-shaped portionoperating through the slot 11, within the divergent portion 15. Thejaw-carrying end of the shank 20 is supported on the ivot 14.

Within the offset portion 1 7 there is disposed the forward end 24 ofthe handle shank 25, said end being in the form of a segmental gear 26,which meshes with the teeth 23. On the handle shank 25, adjacent thetoothed portion 26, there is formed a projection 27 which is arranged tobe engaged by the thumb or finger of the hand of the operator who graspsthe handle shanks 19 and 20. Disposed through the center of the toothedportion 26 is a pivot 28, the opposite ends of which lie in the arcu--ate slots 16, whereby the said portion 26 is capable of pivotalmovement, when in mesh with the portion 22, to cause the member B torock on its pivot and move the jaw 21 toward and away from the jaw 12.

Normally, when the handle shanks 19 and 25 are pressed toward eachother, the member O slides forwardly until the ends of the pivot 28 liein the forward ends of the slots 16, whereby the action of the teeth ofthe portion or gear 26 operates upon the rack 22 to swing the portion Band move the jaws into engagement with a piece of work. WVhen it isdesired to release the jaws from the work, the operator places the thumbof the tool gripping hand on the projection 27 and draws the member Oinwardly through the hand, with the result that the pivot 28 will slidein the slots 16, thereby disengaging the member B from the rack of themember A. Upon placing the thumb against the projection 27, end pressingforwardly, the member C may be moved forwardly to engage the teeth ofthe gear 26 with the rack teeth 23.

What is claimed is:

1. A tool comprising a shank having a jaw and a handle, a second jawmovably carried by the shank, and a second handle slidable into and outof operative engagement with the said second aw.

2. A tool comprising a shank having a jaw on one end and a handle on theother end, a second jaw pivotally mounted on the shank for movementtoward and away from the first jaw, and a second handle slidable on theshank into and out of operative engagement with the pivotally mountedjaw.

A tool comprising a member having a shank and a jaw, a member pivotallysupported on the first member and having a jaw on one end and a rack onthe other end, and an operating member pivotally and slidably mounted onthe first member and having a toothed portion engaged with said rack forrocking the member first pivoted and the jaw carried thereby, and forslidable movement longitudinally of the shank member to engage anddisengage its toothed portion with respect to the said rack.

4. A tool comprising a member having a jaw and a central longitudinalslot, a jaw carrying member in said slot and pivotally mounted on saidmember, the jaw carrying member having an arcuate rack, and an operatingmember pivotally supported on the first member and having a gear portionengaged with the said rack, said operating member having a pivotslidably engaged with the first member whereby to permit movementthereof into and out of engagement with said rack.

5. A tool comprising a member having a longitudinal slot and a jaw onone end and a handle shank on the other end, a jaw carrying memberpivotally supported in said slot and having an arcuate rack on one end,said first member having transversely alined arcuate slots, an operatingmember in said slot and having a pivot engaged in said slots and 'ahandle shank, the pivotal portion of the operating member having a gearmeshing with, said rack, and a projection arranged to be engaged by thethumb of the operator for moving the operating member into and out ofengagement with said rack.

In testimony whereof, I afliX my signature.

CHARLIE WV. SCOTT.
